Insulation overhead crane Overview

An insulated overhead crane is a double girder overhead crane with an insulated Crane Hook, which is different from a standard hook double girder overhead crane. The insulated hook overhead crane is a material handling equipment used to lift and transport loads in live environments, such as factories for electrolytic magnesium, aluminium and other non-ferrous metals. The crane is composed of four major parts: box girder, bridge structure, travelling mechanism, trolley and electrical equipment. During operation, to prevent the current on the live parts from being transmitted to the crane through the workplace and endangering the life safety of the operator, Reliable insulation devices are installed at appropriate locations on the crane. An isolation crane is a heavy-duty overhead crane with double brakes for safety when lifting. The lifting capacity of the isolation crane ranges from 5 tons to 50 tons, and the working level is A6. All operating actions of the crane are controlled from the cab.
